“All hell was breaking loose in a way I had never seen in my career,” Moses says. FrontPoint was net short the market, so this total collapse should have given Moses pleasure.... [But] “I spent my morning trying to control all this energy and all this information,” he says, “and I lost control. I looked at the screens. I was staring into the abyss. The end. I felt this shooting pain in my head. I don’t get headaches. At first, I thought I was having an aneurysm.”

Moses stood up, wobbled, then turned to Daniel and said, “I gotta leave. Get out of here. Now.” Daniel thought about calling an ambulance but instead took Moses out for a walk.

Outside it was gorgeous, the blue sky reaching down through the tall buildings and warming the soul. Eisman was at a Goldman Sachs conference for hedge fund managers, raising capital. Moses and Daniel got him on the phone, and he left the conference and met them on the steps of St. Patrick’s Cathedral. “We just sat there,” Moses says. “Watching the people pass.”

This was what they had been waiting for: total collapse. “The investment-banking industry is fucked,” Eisman had told me a few weeks earlier. “These guys are only beginning to understand how fucked they are. It’s like being a Scholastic, prior to Newton. Newton comes along, and one morning you wake up: ‘Holy shit, I’m wrong!’ ” Now Lehman Brothers had vanished, Merrill had surrendered, and Goldman Sachs and Morgan Stanley were just a week away from ceasing to be investment banks. The investment banks were not just fucked; they were extinct.

Not so for hedge fund managers who had seen it coming. “As we sat there, we were weirdly calm,” Moses says. “We felt insulated from the whole market reality. It was an out-of-body experience. We just sat and watched the people pass and talked about what might happen next. How many of these people were going to lose their jobs. Who was going to rent these buildings after all the Wall Street firms collapsed.”
